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. 

In this case it is recommended to save your data and start the program again. In most cases this error does not result in any loss of data. 

Some materials do not support Tangent predictor. Elastic stiffness is used instead. This concerns the following material types: CC3DCementitious, CC3DNonLinCementitious where the tangent stiffness is supported only for cracking. CC3DBiLinearSteelVonMises, CC3DDruckerPragerPlasticity where the tangent stiffness is not supported at all. 

The material models 3D Cementitious(CC3DCementitious) and 3D Non Linear Cementitious(CC3DNonLinearCementitious) exhibit unstable behavior when the material parameter "fixed crack model coefficient" (FIXED) is not equal to zero. Therefore it is currently recommended to use 0.0 for this parameter.  

The material parameter k for the Drucker-Prager material model is incorrectly generated and in addition the program wrongly requests this value to be negative. This problem will be fixed soon, but currently it can be only bypassed by manually editing the input file for the nonlinear analysis. The input file editing is activated if an appropriate check box is selected in the menu Options || Settings.
