Hi all,

For postprocessing purposes of many cases I want to use one macro to extract information depending on certain conditions, here which physics model is used: inviscid or not.

At the moment my macro looks like:


if ( physicsContinuum_0.getModelManager().hasModel(Invi scidModel.class) = true) {

do stuff }

else { do stuff }

I have troubles debbugging the last method hasModel(..) and the true condition; replacing it by enabled didn't help..
In the case of ... = true the error says that i need a variable and not a value.

Did anyone come across something similar once?

Thanks

There are a few ways (methods) to check whether the model is contained. First, a comment - inside the if statement, you need two equal signs to check whether two objects are the same. So if you wanted to check whether 2 is equal to 1+1, you need to write:

 if(2==(1+1))

Only 1 equal sign will attempt to assign one value to another - in this case, 2=(1+1) would attempt to assign the value of (1+1) to the integer 2, which does not make sense.

To address your question directly, many methods for checking what models exist return a Model object themselves. I would avoid those methods for the simpler .has() method, which lets you specify a string. This macro works to achieve what you want:

// STAR-CCM+ macro: CheckInviscidModel.java
// Written by STAR-CCM+ 10.06.010
package macro;

import star.common.*;

public class CheckInviscidModel extends StarMacro {

  public void execute() {
    execute0();
  }

  private void execute0() {

    Simulation simulation_0 = 
      getActiveSimulation();

    PhysicsContinuum physicsContinuum_0 = 
      ((PhysicsContinuum) simulation_0.getContinuumManager().getContinuum("Physics 1"));

    if(physicsContinuum_0.getModelManager().has("Inviscid")) {
        simulation_0.println("has inviscid model!");
    } else {
        simulation_0.println("does not have inviscid model!");
    }
  }
}

[QUOTE=kirrer;624530] ".has() method "

Hi Kevin, many thanks for this post I will try it out now. Actually I tried also something else yesterday that works but is a bit longer:


Collection<Object> models = physicsContinuum.getModelManager().getChildren();
String Modelnames = models.toString();
Boolean Inviscid = Modelnames.contains("Inviscid");

if (Inviscid == true) {
// do stuff }


and Indeed as I am writing this, your line works well ;-)
