Hi,<\/p>\n

<\/p>\n

I need a modal neutral file (mnf) for rigid-flexible analysis in ADAMS, and I’d like to generate the mnf in workbench. I got a method from youtube on https:\/\/www.youtube.com\/watch?v=-6asFnUr0ac&list=PLhb3ITFxzLNaL35lNzeickBVia7fdfkoF&index. The method involves two main steps:<\/p>\n

<\/p>\n

1. Set two remote points on the aeras which to be the rigid interfaces;<\/p>\n

<\/p>\n

2. Use APDL to generate mnf, the core command is: <\/p>\n

Unfortunately,I didn’t get “file.mnf” which I need, the content of “file0.err” is shown below:<\/p>\n
