how to pickup the mesh data and vector data
I want to know how to pick up the mesh data and vector data from a huge filed.
I am calculating a 10 million mesh model using SimpleFoam.
After that , I want to calculate the Passive Scalar equation on the same model using the U vector data which I calculated.
In the passive scalar calculation , I need just a small part of 10 million meshes.
That's why I want to pick up the mesh data and U vector data in a specific area.
Does someone know how to do it?
maybe you are interested in this discussion
It partly covers the thing you want to do.
Thank you for your advise!
It seems to be helpful for me.
I will try it.
