Cff

There are no options (nor is there any requirement) to determine gradients of CFF. Gradients are available only for field variables. CFF is a field variable but an algebraic one. So, only those...

Uds

This will increase an equation in your case. Fluent solves full conservation equation for UDS. In my view, this would be an overkill just to fetch q-criterion at some points. Secondly, you have to...

Q gradients

As such, q-criterion is not defined as a primitive variable in Fluent. Therefore, its gradients are not available as well. So, the only way is to determine its gradient from its definition (using a...

Q-Criterion

As far as defining a Custom Field Function is concerned, it is easy. You can refer the following

Error

The effect of reading again could cause error if Fluent tries to rewrite a memory while it should not be rewritten. So, instead of reading it using Execute-Command, read it within the journal by...

Journal

I just saw your journal. What is the objective of executing the reading UDF again and again? Are there any changes in the input file? If not, read it just once.

Message

That means it is not even going beyond #if !RP_HOST, which is weird. Did you try this in Serial?

Debugging

Do you get segmentation violation just by running this part of the code? I did not see anything that should cause it but there could be potential bugs, could also be due to version difference....

Point Array and Cell Marking

If all the points are located in a specified region, then Marking the cells is a better idea. Point array would work for a cuboid region, not for a region shaped like a blade, which you most likely...

Arrays and Groups

If the points are not arbitrarily distributed on planes, then you can still go for point arrays and groups. That will reduce the number of monitors as well as number of files. However, now the data...

CFX/ Fluent

I suppose that's subjective. Fluent users find CFX interface rather clumsy. I use both, though more of Fluent. But I have never heard of user interfaces in CFX. Do you mean user surfaces? Or is it...

Monitor Points

For such a high number of data points, it is obvious for any tool to slow down. But the reason is not the tool, rather the machines I/O. For such a work, you need to have hard drive working at the...
