Reactions are always correctly calculated but they can be wr…
  1. inclined supports - only one component of the reaction is shown
  2. for supports close to the reinforcement. part of the reaction that goes into the reinforcement rod is not shown, but it will appear in the textual output in the node that belongs to the reinforcement and is close to the support condition.
  3. reaction at a joint which connects too regions will contain the reaction force only from one region and not the other. This may be especially a problem in case of load-displacement diagram monitoring. It is recommended not to monitor reaction or forces at geometrical joints that belong to more than one region. If it is neccessary then the reaction force should be monitored at all nodes with identical coordinates. The total reaction can be then obtained by their summation.
