Hi,
I have written some Perl scripts occasionally in order to facilitate my job as a CAE-engineer. Everytime I need to sort the results that I have stored in a matrix I have had to make the sorting myself i.e. using some subroutine. However, Id really, really would like to learn how to use the...
Hi all Ansys users!
I have the following problem:
I am trying to run a PSD-analysis in Ansys. I have three nodes onto which I apply base excitations. These nodes are master nodes of CERIG connections. Furthermore, I have lumped masses in my model that are distributed by means of RBE3 elements...
Just as an information to anyone that might be interested. I have found the answer to my question myself; it is possible.

...I do not have neither the time nor the wish to argue about APDL, Classic or whatever. My personal opinion is that both Ansys Classic and WB are cr*p and I do not use neither of them. In this context I mean the GUIs and not the APDL language or the Ansys solver both of which I, as an old...
Hi Drej,
you are absolute right about the functionality in Classic; it is all in there. However, myself I do not use neither WB nor Classic (the GUI) but only the solvers I do my models in Ansa and post-process in Metapost since I think it is the most efficient way to work for my applications...
I have a question about post processing in Workbench:
For various reasons I do not run my analyses from within Workbench (customized Perl scripts that does this and other stuff outside of WB) and I wonder if there is some way of post-processing within WB anyway since classic is a little bit...
I managed to overcome this obstacle at last; changing the UNIX characters < and > for input and output to the -i and -o as used in windows solved the issue.
Case closed.

For various reasons I want to be able to launch Ansys batch runs from Cygwin that I have installed on my Winx64 computer. I have tried many way to do this but no success. I use a command like:
"/cygdrive/c/Program/ANSYS Inc/v130/ansys/bin/winx64/ANSYS130.exe" -j test -np 4 -p stba...
Hi all,
I am fairly new to Ansys but I have been working with Nastran and Abaqus for many years.
One thing that struck me when I started to work with Ansys is that it produce enormous results files.
As of yesterday I computed normal modes 150 ea. for a model with 1.2E6 elements. The results...
...1 > Pfact_mode_1(t)
Participation factor mode 1 > Pfact:mode_2(t)
so that e.g. the stress in node 100 at a specific time t will be:
Pfact_mode1(t)*modal_stress_mode1(node 100)+Pfact_mode2(t)*modal_stress_mode2(node 100)+ + etc for all modes.
I accustomed to use Nastran for this and the...
Thanks kan,
these are some suggestions that I can check out. However, there exist no such toggle then? To force Ansys to continue the pre-check although an error has been found? Just wondering since I am familiar with that behaviour from other FE-codes and its more straight forward. Your...
Dear Drej,
thank you for leading me on the right path. I can not, however, get it to work using /NERR. I run my analysis in batch and in the documentation the following is stated: " A batch run always aborts on the first error."
Is there some way I can override this in order to debug my model...
...messages from Ansys. Suppose that I have a model with some elements that violate quality requirements. E.g. I receive the error message below:
*** ERROR *** SUPPRESSED MESSAGE CP = 105.234 TIME= 16:09:48
Element 210036 has negative Jacobian values at 2 integration points and
the ratio of...
Hi all,
I am an old Nastran a Abaqus user just starting to use Ansys. At the present I have some problems in connection to contact modelling.
First of all; as a newbie I use WB. Eventually I guess I'll start using classic.
However, I have defined contact between two bodies whereof one of them...
Hi,
since SOL103 is the solution sequence for the computation of real eigenvalues i.e. it is a strictly linear analysis you can, per definition, not include contacts. If you have penetrations e.g. shell meshes crossing each other you will have to solve that issue in an other manner than using...
It depends on what you are going to use the sw for. I have used Abaqus and Nastran alot. Personally I think Abaqus is the superior one; better documentation, logical names of keywords, less bugs (my experience).

Hi,
you can easily do that with a, awk or perl hack. If you provide an example of your .pch file I can fix a hack like that for you.

You can always use the *MODEL CHANGE capability on Abaqus/Standard. I do not have the documentation here at the moment and it was a while since I used the feature. Please look into the documentation about the keyword *MODEL CHANGE In princple you do it this way:

Why not install Cygwin on your PC? Then its possible to run Nedit and Perl for example. I use it since I really miss the good old days with Unix
