Something wrong in session-3

When I run this file from 2020-tectonics-modeling-tutorial/session-3/viscoelastic_bending_beam.prm, I encounter the following error, and I don’t know how to solve it. Please help me.
error:Line <146> of file : No entry with name was declared in the current subsection.
original file :

viscoelastic_bending_beam.prm (6.1 KB)

@GWT-Peking The names of input file parameters and sections have changed over time, and apparently the one that the error is about (which the error message you have in your post doesn’t show, but may be set Use stress averaging = false based on the attached .prm file) no longer exists. Have you looked through the changelog files for the last few releases to see what happened to this parameter? We generally document when a parameter name changes, or when a parameter is removed altogether.

Thank you, following your tips, I solved the problem. It was a version issue.
