smartmash element size

abdul8080

Hi everyone, for the simulation of mechanical structures I am using smartmesh and it working fine. However, is there a way to determine the smallest/largest element size used in the simulation??

Hi @abdul8080 ,

You can use *get command to get an element's volume. You can apply a do loop on the elements and store the values in an array (element#, volume) and then check the minimum value.

Can you please give more details. When you say smartmesh, what are you refering to? Also please upload images if possible.

Hello Keyur,

yes I can provide some pics if this helps. Since the spherical void is the region of interest, the mesh there should be fine. In order to use fixed sized mesh, the element size have to be very small and I can only use 8gb. I have used the smartsize command [smrt,1] for this problem, which gives good results and the void region mesh is also fine. I can find out the number of elements used ( LIST -> elements), but I also wanted to know the smallest element size used after the calculation. If there is way to find that out, i would be very thankful. The script with the commands are the following:

/clear

/prep7

ET,1,solid187               

MP,EX,1,205000               

MP,PRXY,1,0.33 

cyl4,0,0,50,,,,100

local,11,0,0,0,50

wpcsys

sph4,0,0,5

vsbv,1,all

!ESIZE,2.5

SMRT,1

VMESH,3

!EREFINE,ALL,,,1

SFA,2,,PRES,-20

DA,1,ALL

/SOLU

SOLVE

FINISH

/POST1

WPOFFS,,,2

!WPROTA,0,0,0

/CPLANE,1         ! Cutting plane defined to use the WP

/TYPE,1,5 

/EDGE,1,1,45
