    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

> I am running a model with polyhedra particles.

would it be possible to create a MWE [1] reproducing the problem?

> what is this?

the only way to find the problem is to have a look at the code..
The source of the problem is in [2], solution of 3x3 system of linear equation. The error is because the determinant is 0.
The solution is used at [3] to test for edge / face intersection (?).

> and why it is displayed in each line?

what does "each line" mean? many times? If yes, it is because the error
is encountered many times..

cheers
Jan
