Hypermesh, Include Files and Export for LS-Dyna

Recommended Posts

Hey everyone,

I ran in some problems again and wanted to know, if there are easy fixes that prevent me from adding too many manual changes to my include keyfiles.


In Hypermesh, I set up a model for LS-Dyna with a tree structure of include files. Some include files are positioned with the Transformation Manager (*INCLUDE_TRANSFORM).

I have two issues at the moment:


1) Remove Transformation

I imported a model as an include and then added a transformation to it. The include type changed from 'Include' to 'Include_Transform', that worked fine. After some more changes, I wanted to change the type back to 'Include'. I deleted the transformation in Transformation Manager, but the type is still 'Include_Transform' now I have the issue that upon export, there is no '*INCLUDE' or '*INCLUDE_TRANSFORM' keyword written in the keyfile.

How can I change the include type back?


2) Prevent export

I have an include file, which is structured in another include file (e.g. in my master file it says '*INCLUDE file_a' and in file A it says '*INCLUDE file_b'.

Now I unchecked the export box in the model browser for file B, because I do not want it right now. File B is rightly not exported, but in file A it still says '*INCLUDE file_b', which gives me an error message, since file B does not exist.

How can I prevent this error from happening?

Edit: I found a solution. Simply check a box at 'Remove include file reference based on export status' which you can find under Export Browser > Solver Options.


Thank you in advance :)

Hi Rahul, thank you for your reply.


My HM version is 2017.2 with user profile LS-Dyna Keyword 971_R8.0.


What do you mean by query 2? I do not have error messages in hypermesh. It exports without error messages. The result from issue #1 is that there is an *INCLUDE keyword missing and the result from issue #2 is that there is an *INCLUDE keyword for a non-existant include file.


The only error message I get is from LS-Dyna solver and it says it could not find the include. This is the result from issue #2 and makes sense.


My questions focus on the export from hypermesh, where those two issues happen without error message.
