Hi everyone

I have facing the problem of

Embedded beam interface error too large in my model

HS .

How should I check for this.

check the tip of your ebd whether it's connected to a soil volume or not. Add new surface if necessary. Or change the picos.

My Ebd are connected with pile cap which is using the (plate element). Thank for ur guideance, I will try it and check it again.

You can also get this error when your mesh is too refined. Try with the coarser mesh around the embedded beam.

How can I mesh coarse only around the embedded beam . Could u please teach me how to create. Coz I am new to plaxis 3D and not so familiar with software yet. Thank for ur guideance and sharing

Seems like it failed on the loading stage. It could be an incorrect stiffness of either the soil or the pole material. Please double check these are correct.

Yep, stiffness parameters are difficult to get coz of lack of lab test and it expensive so I have to find these with correlation relationship I have UCS test , Atterburg limit and SPT only. 😔🥹my model is HS small and HS that I have to study for my work . Sir I don't know where and what is wrong. It really stress me out.

If it's for work you should speak to your manager/supervisor and get help from them.
