General moving objects, flow 3d

Alqadami Ebra · January 8, 2019, 22:54

I am doing CFD simulation related to car stability in floodwaters. I inserted 2 components as a geometry one for the car and the other for the road. I assigned the car as a moving object "coupled motion" with density of 0.9 g/cm3 and the road as non moving body as shown in photo(1).

When I run the simulation the result shows that the car is moving down and penetrate the road surface, please refer to photo (2).

Please any help related to this problem. How can we define the road as a fixed support.

Thank you.

Activate the Collision model inside the General Moving Objects model, otherwise, components can penetrate or overlap each other.
