Combined Load Cases

We are combining a model involving multiple load cases by using the comblc.exe file via the command prompt

(Autodesk Simulation is closed)

By executing the following command:


comblc Test.clc 

(where test Test.clc is a text file refering to the required combination of load cases)


This will generate a results file for the combined load cases. For comblc.exe to work (via the command prompt) a small number of dll files (~10) must be in the same directory as the comblc.exe file.

Howver, we've noticed that when using the latest version of comblc.exe (AutoCAD Simulation 2013), no results file is produced.

At present we are using an earlier version of comblc.exe, which seems to work (the dll files are also the earlier version).


Is there any way to use comblc via the command prompt with the latest version of comblc.exe?


Secondary to this, I've also noticed the stress data ouput file 'ds.s' is not calculated using comblc.exe (even through it is output in the base cases).

Hi Mike,


What you may need to do is use this command at the command prompt:


"C:\Program Files\Autodesk\Simulation 2013\comblc.exe" test.clc


where the path to comblc.exe is where the software was installed. This assumes that the command prompt is set to the same directory that contains the test.clc file, and the text within test.clc must include the path to the files being combined.


Otherwise, I tried it with my 64-bit Windows 7 computer and had no problem with it running.


The basic thing that comblc does is multiply and add numbers together. It really has no idea what it is combining, so it cannot produce the ds.s file, which has a header indicating what each column of numbers represents. Only the processor knows what the result file contains.


Instead, you can run the program "C:\Program Files\Autodesk\Simulation 2013\mkaso.exe" to convert the binary stress results to a text file. I am not sure whether this outputs any headers, but you should be able to figure out the contents by comparing it to the ds.s file.
