Hi I am doing sliding mesh analysis for 5 blade radial fan, while solving i am getting an error as "Severe distortion in specified mesh", can anyone know how to solve this type of error
That would generally mean the setup is not suitable for your desired simulation. If it's a fan with just basic rotation, mesh distortion errors usually mean the motion/model is not correct. You need to have a volume around the fan that rotates as a rigid body with the blade. Check this tutorial: https://help.altair.com/hwcfdsolvers/acusolve/topics/chapter_heads/acu_tut_5001_r.htm
