How to mesh solid blocks?
How to mesh solid blocks?
(OP)
I am a new user of Ansys Mechanical APDL (or any other FEA software). I am performing a thermal analysis of a concrete block (poured over an old concrete block) for 120 hours after casting. The temperature distribution inside the new concrete block will vary according to the internal heat generation rate, the ambient temperature, and the temperature of the old block at the bottom.
I need to mesh the two blocks in such a way that both blocks have the same nod location at the contact surface (for the cold temperature of the old block to be transferred to the new block). Any ideas on how to do this? How do I mesh the two blocks so that the temperature of the cold block below acts as a thermal load to the new concrete block above? Do element sizes have to be the same at the contact surface? How?
PS: I created the two blocks using the solid block command in Ansys Mechanical APDL.
Thank you very much!

RE: How to mesh solid blocks?
please take a look a CONTA173 or CONTA174 elements. Thy should have a key option for TEMP DOF. Then you can use contact elements to bound the two volumes at the interface. Element size does not have to be the same.
