executing a script to output nodal locations at time 0 before moving mesh

tricha122 · October 20, 2020, 09:28

Hi,

i have a moving mesh with a UDF that ouputs HTC's every X timesteps beginning at timestep Y (after mass flow ramping and rotation ramping).

However, by the time my mass flow and rotation are fully ramped, the mesh is in a different position than the starting position, and is erroneous for mapping to the ANSYS thermal model.

I am looking to execute my UDF (DEFINE_ON_DEMAND) at time zero, and not repeat. how can i do this with the TUI?

currently i execute the following after several rotations (ramping flow rate, and ramping speed):

/solve/execute-commands/add-edit execUDF (rpgetvar'storeudm) "time-step" "/define/user-defined/execute-on-demand "on_demand_calc::HsgUDF""
/solve/execute-commands/add-edit execWRITE (rpgetvar'storeudm) "time-step" "/file/export/ascii hconv_data_%t.csv inflation-rotat_oil_1_elem inflation-static_oil_1_elem inflation-static_oil_2_elem () yes udm-0 () no"

Im hoping to be able to execute the two commands above just prior to my initial solve but not "repeat" so i dont get thousands of files

Any help would be greatly appreciated!

Thanks!

nevermind, i think i just needed to do this prior to solving:

/file/export/ascii hconv_data_%t.csv inflation-rotat_oil_1_elem inflation-static_oil_1_elem inflation-static_oil_2_elem () ()
