Hello,

I'm running simulations using Simo Wong method with a convergence criteria of 1E-5 for rigid body motion (immersed solid). In the rigid body convergence plot below, the torque convergence is at 1E-2 even though I set the iteration convergence to 1E-5. Is there another settting under "Rigid Body Control" tab or elsewhere for torque convergence crietria? Thank you!

Hi Vinnakbm,

You can try increasing the max.coefficient loop. Max Coeff loop value might be preventing the solver from reaching the desired convergence so increasing this will ensure that residuals drop to lower values.

Thank you! I did increase the coefficient loops to 50. There is no change because the solution is converging within 10 loops. Any other suggestions?
