ElectrostaticPhys: equation and constants

Asked by YUFAN ZHAO

Hello everyone,

 I got some trouble in reading the ElectrostaticMat.cpp/.hpp files.

 1. If I want to use the value of Z (double layer interaction constant) determined by the physical properties, what is the correct format for using the "getInteractionConstant" command within "Ip2_ElectrostaticMat_ElectrostaticMat_ElectrostaticPhys" ?

 2. What do the physical properties (epsr, z, phi0) mentioned above mean?

 3. Is there any literature (reference) explaining the material law (model) used in ElectrostaticMat?

Thanks in advance,

Best regards,
Yufan Zhao

Hi,
This is a work in progress yet unpublished.
I would suggest to postpone questionning it. :)

Hi,

As Bruno said, this was a work in progress and this will be deleted soon, as a more general framework will replace this stuff (generic lubricated interaction with potential between particles). For more informations, see branch "potential" on gitlab (pkg/dem/LubricationWithPotential.{cpp,hpp})

Better is to not use this contact law for now. I hope the new branch to be released within 2 weeks (after tests).

William.
