When compiling a model of us, it gives the following error:
Invalid setting in 'Parameter_estimations' for parameter 'InitialCondition'. Caused by: Model arguments can not be used in non-tunable expressions. The expression '[0 Parstruct.P]' in parameter 'InitialCondition' of 'Parameter_estimations' can not be tuned but it refers to variables (Parstruct (model argument)). For more information about non-tunable expressions, see the documentation. The generated code will inline the numeric value of the expression '[0 Parstruct.P]' (used in parameter 'InitialCondition' of 'Parameter_estimations') because the expression has one or more unsupported operators (see the documentation). The code for this block will not use the tunable variables (Parstruct (model argument)).
We use a set of referenced models which inherit their parameter structure (in this case Parstruct) by using a mask as model workspace and assigning the structure in the mask of the referenced model. Whenever we want to build code for, i.e., ROS or DSPACE, the above error occurs. How can we solve this?
