I am using FLAC3D version 3.1. I want to model a sphere in FLAC. Please give some suggestion. Thank you in advance.
you can use this Fish function
(User’s Guide manual)
define make_sphere
; Loop over all GPs and remap their coordinates:
; assume len>rad
local p_gp = gp_head
loop while p_gp # null
; Get gp coordinate: P=(px,py,pz)
local px = gp_xpos(p_gp)
local py = gp_ypos(p_gp)
FLAC3D Version 4.0
3 - 20 User’s Guide
local pz = gp_zpos(p_gp)
; Compute A=(ax,ay,az)=point on sphere radially "below" P.
local dist = sqrt(px*px+py*py+pz*pz)
if dist>0 then
local k = rad/dist
local ax = px*k
local ay = py*k
local az = pz*k
; Compute B=(bx,by,bz)=point on outer box boundary radially "above" P.
local maxp=max(px,max(py,pz))
k = len/maxp
local bx = px*k
local by = py*k
local bz = pz*k
; Linear interpolation: P=A+u*(B-A)
local u = (maxp-rad)/(len-rad)
gp_xpos(p_gp)=ax+u*(bx-ax)
gp_ypos(p_gp)=ay+u*(by-ay)
gp_zpos(p_gp)=az+u*(bz-az)
end_if
p_gp=gp_next(p_gp)
end_loop
end
return
Hi,
This fish function just models an spherical excavation. You should modify this function for your works.
Dear all,
I'm trying to model a compactor drum in Flac 2D. Is there any idea to model a cylindrical steel shape in Flac 2D?
Since I didn't find a way to do a cylindrical steel drum in FLAC, I used beam structural elements to model the drum, but I need to make the connections between beams to be rigid. Does anyone know how to do a rigid connection between beams?
Thank you in advance for your help.
