Hi

When I put a constant velocity at inlet face, the initialization can be done

However, when I put a defined log profile velocity at inlet face, divergence is found

Anyone can explain it?

Thanks in advance

It's not something strange. You're making a mistake and your UDF involves a serious error. That's it. Maybe you didn't hook it up correctly. But, I suppose there' s something wrong in your UDF.

Hi

You are right

I found one mistake in my UDF

I forget to modify the position vector

Thanks anyway
