SPH methods¶
- class pNbody._sph_mixin._NbodySphMixin¶
Bases:
objectProvide SPH functions for N-body simulation particles.
- ComputeDensityAndHsml(pos=None, Hsml=None, DesNumNgb=None, MaxNumNgbDeviation=None, Tree=None)¶
Compute Density and Hsml (for a specific place)
- ComputeRsp(Nngb=5)¶
Compute a value for self.rsp base on the distance to the Nngb neighbours This function is not paralellised.
- ComputeSph(DesNumNgb=None, MaxNumNgbDeviation=None, Tree=None)¶
Compute self.SphDensity and self.Hsml using sph approximation
- InitSphParameters(DesNumNgb=33, MaxNumNgbDeviation=3)¶
- SphEvaluate(val, pos=None, vel=None, hsml=None, DesNumNgb=None, MaxNumNgbDeviation=None, Tree=None)¶
Return an sph evaluation of the variable var
- getTree(force_computation=False, ErrTolTheta=0.8)¶
Return a Tree object
- get_rsp_approximation(DesNumNgb=None, MaxNumNgbDeviation=None, Tree=None)¶
Return an aproximation of rsp, based on the tree.
- real_numngb(num)¶
number of particles wor wich r<h
- setTreeParameters(Tree, DesNumNgb, MaxNumNgbDeviation)¶
- usual_numngb(num)¶
usual way to compute the number of neighbors
- weighted_numngb(num)¶
num = particle where to compute weighted_numngb see Springel 05
