Defining Source Term at a Node

Holagee · February 21, 2019, 06:09

Greetings all

I want to implement a source term (electric force) to a group of nodes in a region. When I looked at the UDF manual, all the examples are based on applying forces to group of cells. So is it possible to loop over the nodes of a specified region?

it is possible to loop over nodes

Code:

c_node_loop //nodes in cells
f_node_loop //nodes in face

however, DEFINE_SOURCE macro is executed inside cell loop (no option for nodes there)
So you should think about, how you will apply calculated forces

best regards
