I'm modelling a half RC beam, as shown.
This is the material command for concrete:
This is the material command for reinforcement:
1. For concrete, Patch conforming method, tetrahedrons, element midside nodes dropped.
2. For reinforcements, Body sizing, 1mm, soft behaviour.
Symmetry: Symmetric region applied at the face of the middle of the beam.
1. Solver controls
Solver type, weak springs- program controlled, large deflection & intertia relief- off.
2. Non-linear controls
Force & displacement convergence- on. The rest under non-linear controls are program controlled.
Displacement applied on the edge of "add frozen" concrete body. Free only at x-direction, constant at y & z direction.
*** ERROR *** CP = 18.422 TIME= 21:23:01
Solution not converged at time 1 (load step 1 substep 1).
*** WARNING *** CP = 18.422 TIME= 21:23:01
The unconverged solution (identified as time 1 substep 999999) is
output for analysis debug purposes. Results should not be used for
any other purpose.

RESTART BY RE-RUNNING THE ANALYSIS
Above are the details of the model settings, which doesn't yield proper result. Please guide me through my problems. I'm not sure how to rectify the error.
Below are the deformation response under this setting:

In Workbench, under Analysis Settings, turn on Auto Time Stepping.
Set the Initial and Minimum Substeps to 100 and the Maximum Substeps to 200.

You have to set the Mesh Element Order to Linear if you want to use 8 node hex elements and you have to set the Element Order to Quadratic if you want to use 20 node hex elements. You have left it Program Controlled and it meshed with an element order that does not match the SOLID65 element type. Furthermore, if the element type is only a Hex element, you can't allow the mesh to have any Tetrehedral shapes (and vice versa).
SOLID65 is an obsolete element. I can't even find it in the 2019 R3 help system. Consider changing to a current technology element.

SOLID65 is a Linear element so set the Mesh to use Linear elements.
