User sub routines (Groovy): How using paramIOCurrent[k,v]?

Example

In the directory “…\Flux_12.0\Resources\UserFunction\Examples”, open the Flux project “MaterialLaw.FLU”. Save the project under another name in your working directory.

Using a “paramIOCurrent [k, v]”

In this project, follow the instructions above:

Step Action
0 Delete all project results Solving > Delete results > Delete all project results
1
  • Create a I/O parameter controlled via a scenario
  • Name it “ MU_VAR ”
  • Add reference value 5000 for example…
2
  • Modify the material “ MAT_1”:
3
  • In the tab “ User Coefficient ”, select a “ non linear property ”
  • Delete the value 5000 in the list of USER COEFF /
4
  • In the tab “ User Coefficient ”, select a “ non linear property ”
  • Delete the value 5000 in the list of USER COEFF /
5

Create a new scenario “MUR_VARIABLE” where ìr would be a physical parameter. In this example, “MU_VAR” take a list of values from 1 to 5000 (See the python script in (6))

(list of values: 1.0, 30.0, 50.0, 100.0, 150.0, 200.0, 300.0, 400.0, 500.0, 600.0, 700.0, 800.0, 900.0, 1000.0, 2000.0, 3000.0, 4000.0, 5000.0)

Back to the “ MAT_1” definition and click on the “ Edit user function ” to see and modify into the python editor the groovy sub routine.

These files are in the directory : “....YOUR_FLUX_PROJECT.FLU\persistent\groovy ”
8

Type the following groovy code in the sub routine “ compute ”( public void compute()).

The parameter user is paramIOCurrent“Mu_var”.

Note: In the key “Mu_var” the first letter is writing with an upper case and the following, in lower case.

Plot the Flux through the coil versus ìr by ploting the curve of flux through the coil (2D Curve (I/O parameter) > Circuit > COILCONDUCTOR > Flux [Wb] > Add)
