Hello, FF++ developers!
I would like to do structural analysis of elastic bodies with different material constants in different regions.
When creating a mesh with the square command, the [region] can be set, but this is not possible with the [buildmesh] command.
How can I do it?
I am considering the analysis of an elastic body with a region (A, B) having two different material constants, with the description of the equation as shown below.
solve Elasticity ([uu, vv], [w, s])
= int2d(th,regionA)(
lambda*div(w,s)*div(uu,vv)
+ 2.mu( epsilon(w,s)'epsilon(uu,vv) )
)
+int2d(th,regionB)(
lambdadiv(w,s)*div(uu,vv)
+ 2.mu( epsilon(w,s)'epsilon(uu,vv) )
)
+ int2d(th)(
- gravitys
)
+ on(1, uu=0, vv=0)
;
Thank you in advance.
