How the force on boundary particles are computed

In the file "Post-processing calculations" page 12, it introduces how the force applied from fluid particles to boundary particles are computed. However, when I go to the source code I could not find where dv/dt for boundary particles are computed. For Non-newtonian fluid I guess the function to do the job is: JSphCpu_NN_SPH.cpp:InteractionForcesBound_NN_SPH. I assume that in the function I could find a variable called "acep1", which is dv/dt for boundary particle p1. I could only find "arp1" (drho/dt) but not acep1.



  • Or maybe this step is done in the binary file ComputeForces_linux64 whose source code has not been released?
