Thank you for the suggestion. I followed the tutorial and now the contact in the fluid component (FLUENT works fine as I can see the grid/cells being deleted when the contact is activated using a proximity threshold (0.004) defined in FLUENT. However, now the solid component (transient structual) throws a "highly distorted elements" error when the flap reaches the contact (defined by offset value of 0.001 in solid solver). Please seee the attached figre for reference. I beleive the contact force is significant that it deforms the flap. Is there a way to reduce the contact force or fix this "highly distorted elements" error. I have tried different contacts such as frictionless as well as friction contact, but nothing helps so far. Hoping to hear from you soon.
