How to read the material properties of components with TCL

I want to create a text file with the volumes and material properties of all the components in my model.

 

I'm using this code to extract the volume: 

 *createmark solids 1 all set solid_list [hm_getmark solids 1] foreach solid $solid_list {    *createmark solids 1 $solid    set vol [hm_getvolumeofsolid solid $solid]    puts '$vol' }

 

How can I extract the density (rho), modulus of elasticity (E), and Poisson's ratio (nu) from my components?

Thanks.

    these material properties are related to your material, so you should extract them from your material data, according with your solver for some cases, using hm_getvalue. For these 3 listed in your case, it is possible to get them directly like this.

     

    hm_getvalue materials id=$matid dataname=youngsmodulus

    hm_getvalue materials id=$matid dataname=poissonsratio

    hm_getvalue materials id=$matid dataname=density

     

    Can you try it?

    Or if you want to retrieve from the component, this might work (have to test this).

    hm_getvalue components id=$compid dataname=material.youngsmodulus

    The material data is linked to elements via Property.

    Thanks Adriano, that was what I needed to get it working as shown below:

      

     *createmark comps 1 all set comps_list [hm_getmark comps 1]  foreach comp $comps_list {    *createmark comps 1 $comp     set compname [hm_getcollectorname comps $comp]    set matname [hm_getvalue components id=$comp dataname=material.name]    set mat_id [hm_getvalue components id=$comp dataname=material]    set moe [hm_getvalue materials id=$mat_id dataname=E]    set nu [hm_getvalue materials id=$mat_id dataname=Rho]    set rho [hm_getvalue materials id=$mat_id dataname=Nu]        puts '$comp,$compname,$matname,$moe,$nu,$rho' }

     

     

    Thanks
