Hi,

When creating contact there's a definition called 'trim'. In the documentation it is said: 'The contact surface elements will be trimmed based on following trim option selected..'

but the documentation doesn't explain what trim is.

 

Can you please assist?

    Hello, 
    Trim means that for the contact it will not be considered only a WHOLE face, or a set of whole faces, rather will be used if necessary only a portion of a face, using only the elements which are interested.

     

    WHithout the TRIM option, a whole face will be included in the contact, as soon as one element of the face is included.

    Thank you for the information.

    I now understand what trim does.

    I highly recommend to include these features in the documentation. Otherwise it is almost impossible for the user to use it wisely.
