Hello,

How can I create a constraint between a ChNodeFEAxyzrot and a ChBodyFrame (frame) object? (ChLinkPointFrame only works with ChNodeFEAxyz). I tried by using the ChLinkMateGeneric class, since the ChNodeFEAxyzrot inherits from ChBodyFrame, but was not successful. Thanks in advance.

Dear André

the ChLinkMateGeneric should work fine... which type of error do you get? compile time or run time?

Dear Alessandro,

The error was in the way I initialized my ChNodeFEAxyzrot. The ChLinkMateGeneric should works fin. Thank you for the quick response.

Best regards,

André
