When I am trying to export an ADAMS plant, if the adams system has contact forces, the simulink block cannot initialize the system. But when I remove the contact between objects, the Simulink block works well. Any ideas where the problem comes from?

The error message from .msg is as follows:

---- START: ERROR ----

Error: GRAPHICS/432, EXTERNAL has been illegally defined.

External file = Robot10.xmt_txt Part = PART_233 Element = CYLINDER_432

Error code = 1

Please verify that the referenced file is correct, and the format

is supported by Adams. Check the spelling of the file name and

the file protections. Also note that some external geometry files

are not backward compatible.

It might be so simple that the Parasolid file (.xmt_txt) is in the wrong directory.

Open the adm-file in a text editor, search for ".xmt_txt" and remove any path from the file name. Then make sure that it is located in the correct directory.

Thanks for your reply, I appreciate it!

You are mentioning "Open the adm-file in a text editor, search for ".xmt_txt" and remove any path from the file name. "

Can you please explain it a little how I can do this?

Thanks

At first I wondered how someone could not interprete the advice "Open the adm-file in a text editor, search for ".xmt_txt". "

But then I remembered that most Windoze users don't have the slightest idea in which directory ADAMS is executed and thus they don't know where to find their files.

Usually it's your home directory C:/users/<user-name>/, but you can also use the Windows file search and look for *.adm and sort them by date to find where the latest where created.

Check for files with the ending .adm (usually referred to as "the adm-file"), right-click and choose "edit" (which is the most convenient way to edit a file).

If everything was ok, all the other files should be there, too (like the .msg, .res, .xmt_txt, ...)

BTW: Some people would argue that if you found your .msg, the .adm should be a no-brainer

BTW 2: In one of your other posts, I saw that you use blank spaces in path names. That's something that is not always working in ADAMS. Try to run in places that don't use that fuss.

Could you post your adm, acf and .xmt_txt files?
