Adding a particle custom property to heat transfer API

Yangyang_Shen

Hi. I want add a particle custom property that is calculated from the particle temperature. And I took the heat conduction API code in the example  'HeatConductionForGeometry_29July2014.zip' from the page link below:  

https://community.altair.com/community/en/edem-api-contact-model-example-heat-conduction?id=kb_article&sysparm_article=KB0121824

The new custom property, PARTICLE_CONTENT, is a mass property. The PARTICLE_TEMPERATURE and GEOMETRY_TEMPERATURE are from the heat conduction code before. 

const string CHeatConduction::PARTICLE_TEMPERATURE = "Temperature"; const string CHeatConduction::PARTICLE_CONTENT = "Content Particle"; const string CHeatConduction::GEOMETRY_TEMPERATURE = "Temperature Geometry"; 

And I defined PARTICLE_CONTENT as below: 

    if(eParticle == category &&         0 == propertyIndex)     {         strcpy(name, PARTICLE_CONTENT.c_str());         dataType		= eDouble;         numberOfElements= 1;         unitType		= eMass;         return true;     } 

I was able to compile the code, but when I tried to load the library file in EDEM, I got an error message: 

For my simulation, I only selected 2 inbuilt models (Hertz-Mindlin with JKR, Standard Rolling Friction) for Particle-Particle and Particle-Geometry interactions. Also my EDEM deck was created from scratch, so I don't think there's any previously used custom properties. 

Can anyone please help me figure out what I have done wrong? 

Thanks a lot!

Hi,

Could you share your code and model, I can review to see if I can see the issue.  

Just to note I see in the code you share that it defines

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

When you define the particle temperature did increase the property index?  

Regards
