    • Q8.1 Is it possible save a sketch from one model and use it in another model?
    • Q8.2 Can I import a sketch from a different CAE database?
    • Q8.3 I had inadvertently introduced a break in the line in sketcher mode which makes the meshing awkward because a line segment is small and split on one side preventing me from creating a symmetric mesh.
    • Q8.4 Working with small scale CAE in the sketcher mode was making silly mistake in line drawing even though I had zoomed in and using points I had created.
    • 8.5 After sketching and saving and creating a part I wanted to partition it but the points I created as markers did not match the original co-ordinates I had specified.
    • Q8.6 Using the coordinates displayed I created a few points in creating a sketch and I found that these are in the wrong place. I found that the sketch I had made was not accurate.
    • Q8.7 I had imported a geometry from a CAD package. I wanted to make some minor changes but CAE insists that there are no modifiable parts?
    • Q8.9 On sketching a rectangular section with a circular hole I was not able to draw another partitioning circle around the first circle with an idea to specify a finer mesh within that region. But I was not able to do this in one go in the sketcher?
    • Q8.10 On entering the sketch mode to partition a face, the part has been re-positioned so the co-ordinates fo the points I wanted to use were no longer valid. Is there a way around it?
    • Q8.11 All the parts in the assembly appear to be positioned w.r.t to the same origin and had to be translated into position. Is there a way around it?
    • Q8.12 Because of the problem of using the same origin all the part instances are bunched together making it difficult to choose the right instance to move?
    • Q8.13 In sketching an outline which involves a large dimension in one direction and points which are close by makes it tedious to complete the outline. Any way around it?
    • Q8.14In sketching a part if you have incorrectly defined the part it does not seem to be possible to change it. Is here a way around it?
  9. ABAQUS - CAE General
    • Q9.1 In creating a partition I specified an arc which circled the region to make the partition clear but CAE complained about an open curve which needs to be closed.
    • Q9.2 It is sometimes difficult to figure out whether something is possible using CAE or not how can I find out?
    • Q9.3 It is difficult to choose interior surfaces for example in a hollow sphere where pressure is being applied to the internal surface.
    • Q9.4 When I am making selection occasionally make a wrong choice especially if it is string of nodes then do I have to start from scratch?
    • Q9.5 It is easy to instance more than one instance of a part. Not easy to delete it and I tried suppressing it.
    • Q9.6 After analysing the results I found there were more than one instance which was not intended. How do you detect these beforehand?
    • Q9.7 Having carried out an analysis with a quarter model I wanted to analyse the full model. I was trying to copy and translate each quarter and then rotating to make the full model with out the mirroring option at the assembly level. Is there an alternative?
    • Q9.8 I have carried out an analysis with quarter model making use of the symmetry however I would like to be able to display the results on a full model. Is that possible?
    • Q9.9 I have carried out a 2D model. However I would like to be able to display it in 3D so that stress distribution along the boundary can be easily visualised. Is that possible?
    • Q9.10 I would like to merge 2 separate parts which have a common edge but would like to retain the boundary so that I can assign different material properties to the two parts. Is this possible?
    • Q9.11 Can one tie 2 unmatching regions together?
    • Q9.12 How does one model the interface conditions between the 2 regions of a bimetallic strip which are bonded together?
    • Q9.13 I remote login to a server from my PC using X-win 32 and I find that carrying out any work bordering on the impossible when I use zoom in/pan which do not appear to have any effect. It is also tedious/cumbersome to turn the model around (rotate) to specify boundary conditions on the far side/face.
    • Q9.14 When I partitioned a part that had boundary condition, loading and interaction specified on it all got unset and I had to re-specify these again. `
    • Q9.15 I want to be able create a template of various sections and define section properties so that I am able to add the actual members later on. However this appears not to be possible.
    • Q9.16 In applying pressure the wrong surfaces were being picked and since ABAQUS does not have the option to highlight the entity before selection I have to start all over again from scratch. Is there a way around this problem?
    • Q9.17 A previously created and saved CAE file appears to be corrupted when tried to open it subsequently. Is it possible to re-create the CAE file? (27 April 2012)

  21. ABAQUS - Troubleshooting
    • Q21.1While using the Graphics module CAE when expecting a menu page to pop-up got a icon with a Cyan coloured double column. This makes it impossible to progress with the work. What is the problem?
    • Q21.2 ABAQUS 6.4 in installed in a PC running XP. The Graphics module's viewport when moved around leaves a shadow (permanent remainder) on the screen. How does one fix this problem?
    • Q21.3 I have both ABAQUS 6.5.2, 6.6 and PATRAN 2005R2 installed in my PC. How do I get ABAQUS to run from within PATRAN?
    • Q21.4 How do I keep the PATRAN databases compact If I am only using ABAQUS ?
    • Q21.5 PATRAN is complaining about the license server?
    • Q21.6 How do I run a complete verify ?
    • Q21.7 How do I run part of a verify. For example to verify just the standard version ?
    • Q21.8 How do I identify the nodes with warning messages in a completed analysis?
  22. Pre Processing using PATRAN
  23. Post Processing using PATRAN
    • Q23.1 Is it possible to use PATRAN for post processing even if it was not used for pre-processing ie not used to generate the mesh?
  24. Pre Processing using FEMGV
  25. Post Processing using FEMGV
    • Q25.1 Is it possible to produce a 2-plot layout instead of the 1, 4 plot layouts?
    • Q25.2 Is it possible to write out the results of a XY Plot to an external ascii file?
    • Q25.3 Is it possible to read in the results of a XY Plot from an external ascii file?
    • Q25.4 Is it possible to cut open and develop a cylindrical mesh and produce contour plots on the developed flat surface?
    • Q25.5 Is it possible to take an arbitrary line section through a 2D model and display the variation of a selected output parameter (example : von Mises stress) along that line?
    • Q25.6 Is it possible to take an arbitrary section through a 3D model and display contours of a selected output parameter (example : von Mises stress) on that section?
    • Q25.7 Is it possible to produce a contour plot of the un-smoothed stresses?
    • Q25.8 Is it possible to produce a contour plot of the smoothed stresses if only the stresses at the integration points were written to the results (*.fil) file?
  26. ABAQUS - Errors
    • Q26.1 In a 3-dimensional analysis using mixture of elements (CDR8, S4R5 and M3D4) degrees of freedom of M3D4 elements appear to get fixed where these are suppose to be free. Why is that?
