Dear guys
I have a question about getDelta when using calculateForce. Assuming contact of particle 1 with both particle 2 and 3, and calculateForce goes for 1-2 first, then 1-3. So when calculateForce for particle 1-particle 2, the custom property of particle 1, i.e. m_delta_1, is only the increament from interaction 1-3, or already considering the increment from interaction 1-2, as "m_delta_1 +=value" (example) is involved in multi-contacts.
PS: defining:
const double* m_value_1 = elem1CustomProperties->getValue(m_index);
double* m_delta_1 = elem1CustomProperties->getDelta(m_index);
Best wishes
