Pressure-dependent frictional condition can be defined in WB LS-DYNA using Keyword Snippet.
You need to use WB LS-DYNA to create a frictional contact first. Then write the K file and copy the contact keyword to the Keyword Snippet. In the keyword snippet, FS needs to be set to 2.0 or -2.0. You also need to include *Define_Table or *Define_Friction to get the pressure-dependent coefficient of friction. See the instructions below from LS-DYNA K Manual.
Finally, you need to suppress the frictional contact in the WB LS-DYNA Tree Outline to avoid the duplicated definition of the same contact.
