Re: Anti-symmetric loading, symmetric geometry

It can be done. If interested:

 

BUT it is less efficient as there are 4 models run rather than 2 as in the old (version 20 and before?) days

 

Create

 

  • anti-symmetric loadset
  • symmetric loadset
  • anti-symmetric constraint set
  • symmetric constraint set

 

Create 2 analyses

 

Analysis1

 

  • Anti symmetric constraint
  • BOTH loadsets NOT combined

 

Analysis2

 

  • Symmetric constraint
  • BOTH loadsets NOT combined

 

Create STANDARD design study containing:

 

Study1

  • Analysis1
  • Analysis2

 

Run the design study and each analysis will be run for each loadset; 4 analyses.

 

Using the design study keeps the mesh numbering consistent.

Using the design study ensures that all files are called 'STUDY1.xxx'

 

\Study1\Analysis1 subdirectory will contain results for both loadsets against Anti-symmetric constraints

 

  • study1.s01, study1.d01 etc
  • study1.s02, study1.d02 etc  **

 

\Study1\Analysis2 subdirectory will contain results for both loadsets against Symmetric constraints

 

  • study1.s01, study1.d01 etc
  • study1.s02, study1.d02 etc *

 

Manually copy the Analysis2 files ending in *.*02 marked above with *

 

and replace the Analysis1 files marked ** with these.

 

 

A limited methodology.

 

Have fun.
