Difference Between Manual and Computational Calculation Results

I have created a very simple model to check the manual calculation. I cannot get the expected results. Could you please help me?

Answer:

The difference compared to the expected results is due to the calculation of the self-weight of the structure. However, the self-weight acts upwards, so it is subtracted from the resulting reactions instead of being added.

The self-weight load acts in the same way as the positive Y axis. Therefore, the self-weight is subtracted from the support reactions.

For a 2D model of a vertical structure, we recommend using the 2D-XZ model type.
