ANSYS error message
 

Hi,

I recieved the following error (for the structual side) while performing a FSI simulation. Can anyone explain what it means and how to fix it?

Preconditioned conjugate gradient solver error level 1. Possibly, the model is unconstrained or additional iterations may be needed. Try running with a multiplier MULT > 1 in EQSLV command (3 > MULT > 1).

Thanks CC
