Is anyone familiar with using User Defined Functions(UDF) in Discrete Phase Models(DPM)?

I am working with DPM and using UDF. Without UDF my model is working good. When I compiled my UDF I got a warning (image attached) but opened the file. After compilation when I run the simulation,...

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

Ethylene glycol is newtonian or non newtonian fluid?

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.

How are iso-frequency contours plotted?

Let's say we have a standard, regular hexagonal honeycomb with a 3-arm primitive unit cell (something like the figure attached; the figure is only representative and not drawn to scale). The...

I know you can select non-spherical drag force in Fluent

Reyes Andrés

Definitely, it is not possible, but you can incluide the non spherical effect in the drag model through UDF .
