Calculate Iron Losses via python - rounding of input Parameters issue

Hi all,

I want to read the Iron losses, flux is nicely presenting you a comand to do so:

result = IronLossesRegion(faceRegions=[RegionFace['STATOR']],
                 timeInterval=EvolutivePath(parameterSet=[SetParameterFixed(paramEvol=VariationParameter['F'],
                                                                            currentValue=5.0),
                                                          SetParameterFixed(paramEvol=VariationParameter['SPEED'],
                                                                            currentValue=50.0),
                                                          SetParameterFixed(paramEvol=VariationParameter['I'],
                                                                            currentValue=2.428169183),
                                                          SetParameterFixed(paramEvol=VariationParameter['IANGLE'],
                                                                            currentValue=1.570796327),
                                                          SetParameterXVariable(paramEvol=VariationParameter['TIME'],
                                                                                limitMin=0.0173914,
                                                                                limitMax=0.21739)]),
                 curveName='CURVE_LOSS_REGION_1',
                 resultName='LOSSES_IN_REGION_1',
                 lossSpatialParameterName='DVOL_LOSS_MEAN_1',
                 energySpatialParameterName='DVOL_ENERGY_LOSS_1',
                 periodicity=FullCycleIronLosses(),
                 sheetLossModel=CaseDefinedInMaterial())

which works well. But when I now replace the input numbers with my variables I get some trouble. When I provide more or less digits than flux expects I get an error:

Java exception occurred:
rsi.core.common.error.RsiServerException: Can not execute the following command :
result =
IronLossesRegion(faceRegions=[RegionFace['Statorzahn1']],timeInterval=EvolutivePath(parameterSet=[SetParameterFixed(paramEvol=VariationParameter['F'],currentValue=5),SetParameterFixed(paramEvol=VariationParameter['SPEED'],currentValue=50),SetParameterFixed(paramEvol=VariationParameter['I'],currentValue=2.428169183),SetParameterFixed(paramEvol=VariationParameter['IANGLE'],currentValue=1.570796327),SetParameterXVariable(paramEvol=VariationParameter['TIME'],limitMin=1.7391E-02,limitMax=2.1739E-01)]),curveName='CURVE_LOSS_REGION_1',resultName='LOSSES_IN_REGION_1',lossSpatialParameterName='DVOL_LOSS_MEAN_1',energySpatialParameterName='DVOL_ENERGY_LOSS_1',periodicity=FullCycleIronLosses(),sheetLossModel=CaseDefinedInMaterial())

The first two time steps cannot be selected for this

Now when I tweek the the thing a little with the last digits (defneately the same timesteps) it works for one model. Since I want something general that is not a way forward.

Is there a more robust way to calculate the iron loss via code?
