EDEM API :How to assign an initial value to a custom property？

LuBao

Hello everyone, I'm writing an API for particle-geometry collisions. I want the API to record the number of collisions a geometry object undergoes, convert this collision count into heat using a formula, and store this heat in a custom property.

I've already implemented this functionality. Now, I want to assign an initial value-18.5 to the custom property. Could someone please tell me how to do this? I've attached my code, Thanks.

Hi @LuBao,

The custom property initial value can be defined in the getDetailsForPropery function. Here's an example of how to set the initial value of a geometry custom property:

bool CYourCustomModel::getDetailsForProperty(

    unsigned int                    propertyIndex,

    NApi::EPluginPropertyCategory   category,

    char                            name[NApi::CUSTOM_PROP_MAX_NAME_LENGTH],

    NApi::EPluginPropertyDataTypes& dataType,

    unsigned int& numberOfElements,

    NApi::EPluginPropertyUnitTypes& unitType,

    char                            initValBuff[NApi::BUFF_SIZE])

{

    // Define the characteristic of the properties: name, number of elements, unit

    if (0 == propertyIndex && eGeometry == category)

    {

        strncpy(name, PROPERTY_NAME.c_str(), NApi::CUSTOM_PROP_MAX_NAME_LENGTH);

        dataType = eDouble;

        numberOfElements = 1;

        unitType = eMass;


        //Initialize property value. The inital value is defined here

        ostringstream oss;

        oss << 18.5;

        strncpy(initValBuff, oss.str().c_str(), NApi::BUFF_SIZE);

        return true;

    }

    else

    {

        return false;

    }

}
