#### Topic: Model of a Simple axial loaded column doesn't work

Hello,

I want to model a reinforced concrete column with an increasing axial force until a specified load. I modeled the column with smeared reinforcement and add two steel plates to the ends, one for applying the axial load and the other for applying boundry conditions. I apply a point force to the middle of the plate. It seems so simple!

However, when I run the model at the very first step I come to many errors and warnings as :

(*) Warning: Loss of at least 7 digits in reducing diagonal of equation: 1762, (node: 3021, dof_id: 1); value: 179383

(*) Warning: Loss of at least 7 digits in reducing diagonal of equation: 1768, (node: 3003, dof_id: 1); value: 100136

Could anyone provide some comments to solve the problem?
