Connection Of Members Including Solid Ones

Hello,

I try to model a simple beam and solid structural system (see Lesson5_2.rar) . But, I am warmed by an error (see Lesson5_error.jpg).

Altough I serach the element features, I can not find any paramaters under the element property called "option"

best wishings,

If you scroll down to the bottom of the error list, you will see the full traceback of the error, and you will be able to understand better where the error comes from.
Anyways, you are using a DispBeamColumn with an Elastic Section. However, if you using Disp (or Force) beam column elements, you should put the Elastic (or Fiber) section inside a PhysicalProperty->special_purpose->Beam-Coloumn->BeamSectionProperty.
In that property you can define the integration scheme (needed for a Disp or Force beam column) and the section to be used.

Please, watch any of the webinars on beam elements to see this.

Hi, You missed adding beam section property (specifying integration type and number of integration points etc.) in physical properties section for the beam elastic beam section. Please check the attached model.

Dear STKO and Kesavapraba,


Many thanks for your supports.


Your support is really important and valuable for the new users like me.

Now, the model runs witout any error. But, I noticed that there exist a neglected defomation after analysis. Therefore, I change the boundary conditions as fixing the side faces instead of edges, increase the load magnitude and lastly decrease the elasticiy module value (see new model lesson5_3.rar)

However, again this model makes a neglected deformation (see lesson5_3_deformation.jpg). As if there is a problem about the connection of nodal loads with the structural system although the nodal load is defined on the connecting node.

Hi, Some issues with your model are as follows:
1] Use krylov-Newton or other algorithms when MP constraints, like beamSolidCoupling, are used.
2] Not sure why you applied interaction at the top and bottom surfaces. Moreover, the interaction should be between the line element and the face of the solid at the hole, not between the beam line to solid edge! I changed these apsects.
3] Penalty factors are aso important in your model, so pay attention to it.

Please check the revised model attached here.
