mesh generation philosophy
 

i'm new with CFX and i'm lost with the prametres (element,sizes,max....) is there any advice

Re: mesh generation philosophy
 

Elements may be a problem if they have any of:

TETRA:

Edge Length Ratio >100 Max Face Angle >170° Min Face Angle <10° Element Volume Ratio >30 Connectivity Number >50

------------------------------------

PYRA:

Edge Length Ratio >100 Max Face Angle >170° Min Face Angle <10° Element Volume Ratio >5

------------------------------------

PRISM:

Edge Length Ratio >100 Max Face Angle >170° Min Face Angle <10° Element Volume Ratio >5 Connectivity Number >12

------------------------------------

HEXA:

Edge Length Ratio >100 Max/Min Edge Length >100 Min Face Angle <10° Element Volume Ratio >5 Connectivity Number >24

------------------------------------
