I need to store a vector field computed in a UDF to display it in FLUENT. Is it possible to store vectors with C_UDMI? Any advice would be appreciated. Thx a lot

Can you not store the 2 (or 3 in 3d) components of the vector in 2 (or 3) UDMI's

Then how is it possible to plot the vector field in FLUENT ?

You only said store. Not plot. However, you could always create a custom field fucntion. I imagine it would be something like:

(UDMI_0^2 + UDMI_1^2)^(1/2)

That would get you the contours. I think velocity vectors may be more tricky, cerainly beyond my experinece.

1. You can store the component of the vectors in C_UDMI 2. You can define a new custom vector from:

Display->Vectors->Custom Vectors... Here you can put as new vector's components udm[0], udm[1],... ; 3. Suggestion: It is better to keep also in memory the absolute value of the vector and to choose colors using this value.

Good Luck!
