The iteration stops earlier than the set value.

I set the iteration as 30000, but it stops earlier than the set value, and reports "Error in "void CSysSolve::ModGramSchmidt(int, std::vector<std::vector<double> >&, std::vector<CSysVector>&)": ".I want to know how to solve it and finish the whole iterations.

Your simulation has most likely diverged, that is why it stopped. Can you show the last couple of lines of the screen output?

There are many reasons for this. Some things to check:
1. mesh quality
2. Setup of the physics models

3. Setup of boundary conditions and initial conditions
4. Setup of the numerical solver

If you share your mesh and configuration file so the problem can be reproduced, it will be easier to help you solve this issue.
