Question about assign a value to custom property

Raheem Sterling_22160

Hi,

I wrote some custom properties as below:

        m_NormalStressDelta[0] = 1.0;
        double tmp1 = m_NormalStress[0];

but when I debug the code, I saw the values of tmp changes from 0 to 1 to 2 etc. Increasing with time.

But what I want is to give a m_NormalStress a certain value, means 1.0 all the time. But seems that for m_NormalStress it was "+=‘’ with time, not "=" even I wrote like this.

Thanks

Hi,

Custom property deltas are just that, deltas that are added to a value. There is no resetting of the value by default. In your case you're adding 1 to the value every time. If you want to reset the value to 0 before adding your delta, you can either do that in configForTimestep( ) or depending on how you're updating the delta, you can also do:

delta = 1.0 - value;

However, this only works if it's being called once. If there are multiple calls to update the custom property, then you should use the configForTimestep( )->resetCustomProperty approach.
