Hello, does anyone know how to get the results for the entire volume domain automatically generated by ICFD? I need to calculate the shear stresses. For this purpose, I need information about the velocity gradients or shear rate. How to generate this information for each time step?
I will be grateful for every information.

It is usually better to visualize the results on a section of the volume instead of the full volume.
You can output the shear as follows:
An alternative is to output the drag using *ICFD_DATABASE_DRAG. See the user manual for more information.
Let me know if this answers your question on not.

I agree that sometimes it's better to visualize results only for individual sections. In my case, I need this information to use them to calculate other flow equations. Therefore, I need this information in the form of an external file to be able to perform calculations on it.

Have you tried *ICFD_DATABASE_DRAG? See the user manual Vol III for more information. This keyword creates a text file output for the drag force.

The best solution is to calculate the shear stresses in Ensight or Paraview. The topic can be closed.

Thank you for letting me know. I saw that my colleague asked the developer for advice on this. Here is the post for the benefit of other users:
Have a good day!
