[ESPResSo-users] Rigid Objects using OIF

[Wink, Markus]

Dear all,

 

I have worked through the tutorial „object in fluid“ where red blood cells are simulated in a microfluidic channel. The cells are deformable which is accomplished by setting the parameters

“ks 0.07 kb 0.01 kal 0.01 kag 0.01 kv 10.0“

 

I was wondering, how to achieve rigid bodies with that implementation. Concerning the user guide and the article found at arXiv:1312.3426v1, one has to adapt the parameters mentioned above. Anyway, I don’t know which values to take. Having a look e. g. on the stretching force Fs, ks  describes the stretching constant. Setting that value to 0 results in a vanishing force Fs, thus the triangulation edges will not relax to the relaxed length. That’s exactly the opposite to the rigid body I want to have.

 

Does anyone know, what the parameters would look like for rigid bodies or how to implement it using OIF?

 

Greetings,
