The Level-set function can be accessed using the C_LSF(c,t) macro, where 't' is the phase thread pointer in Fluent.

Fluent / Re: Error: "ST_Create_Store: out of memory" in out file.

« Last post by william on December 27, 2020, 05:18:33 PM »

I am getting the following Error: "ST_Create_Store: out of memory" in out file.

Please tell me how to fix this error.

Thank you.

This error arises because of the system configuration. It also arises when the problem is more complex geometry and complex physics like reacting flows, multiphase, CHT etc.
In case of heat transfer when the user tries to solve convection then the simulation will work fine but if radiation is also involved then this error arises.
Hence it is recommended to use high end configuration system.

Ansys Fluent has inbuilt compiler in 2020R2. Instead of Visual studio compiler, you can select "Use Built-In Compiler" after selecting the UDF file and then click the build button.

Fluent / Re: Can I get the number of faces in a boundary zone to use it in a variable?

Hi,

How can I get the number of faces in a boundary zone to use it in a variable in Fluent?

Thanks.

Create a variable, then use the following Scheme code snippet

(define (ncf ct_id) (car (%inquire-faces-and-nodes-on-thread ct_id)))

Then just use

(ncf 4)

to get the number of faces in thread with ID 4.
