Initial velocity for the internal mesh

ali_b124 · June 3, 2021, 05:06

Helle team REEF3D,

Is there any option to give an initial velocity for the internal mesh?

We are already give velocity for the inlet but i want to start to simulation while all the internal nodes have a velocity value. Is that possible?

Thank you and best regards.

For initializing the velocity field, the recommended way is to employ the potential flow solution. You turn this on by using I 10 1. This should be used together with ioflow (B 60 1).
