record arrays produce overdetermined system
record arrays produce overdetermined system
Dec-22-11 20:54:20
Hello,
I have the following problem:
When I define arrays of records within a record,
they produce equations and the following model which needs the containing parameters
cannot be simulated. It works in the Dymola demo version.
Code:
package OMtest
record MyGenericData
parameter Integer dataOne;
parameter Integer dataTwo;
end MyGenericData;
record DataSetOne = MyGenericData(dataOne = 1, dataTwo = 2);
record DataSetTwo = MyGenericData(dataOne = 3, dataTwo = 4);
record MyDataArrays
parameter Integer dimension = 2;
DataSetOne dataSetOne;
DataSetTwo dataSetTwo;
MyGenericData dataArrayOne[dimension] = {dataSetOne, dataSetTwo};
end MyDataArrays;
model MyTestModel
MyDataArrays myDataArrays;
Integer oneVariable;
equation
oneVariable = myDataArrays.dataArrayOne[1].dataOne;
end MyTestModel;
end OMtest;
Any idea when this will be fixed? Thanks!
Fritz
Hi again 
, I hope nobody is answering here because of Christmas and New Year...
Anyway, this does neither work:
Code:
package OMtest
record MyGenericData
parameter Integer dataOne = 1;
parameter Integer dataTwo = 1;
end MyGenericData;
record DataSetOne = MyGenericData(dataOne = 1, dataTwo = 2);
record DataSetTwo = MyGenericData(dataOne = 3, dataTwo = 4);
model MyTestModel2
DataSetOne dataSetOne;
DataSetTwo dataSetTwo;
replaceable MyGenericData dataSetArray[:]={dataSetOne, dataSetTwo};
Integer result;
equation
result = dataSetArray[1].dataOne;
end MyTestModel2;
model MyTestModel2TestModel
DataSetOne dataSetOne;
DataSetTwo dataSetTwo;
//MyTestModel2 testReplaceable(redeclare MyGenericData dataSetArray = {dataSetTwo, dataSetOne}); // this gives a type mismatch error although there shouldn't be any!
MyTestModel2 testReplaceable2(dataSetArray = {dataSetTwo, dataSetOne}); // this gives no error, only has too many equations for simulating
end MyTestModel2TestModel;
end OMtest;
I would really need this type of code. Any comments are welcome.
Thanks, Fritz

hello again,
I finally found out how to solve problem 1 with the overdetermined system. within the record MyDataArrays the keyword parameter has to be used again!!! this works!
Code:
record MyDataArrays
parameter Integer dimension = 2;
parameter DataSetOne dataSetOne;
parameter DataSetTwo dataSetTwo;
parameter MyGenericData dataArrayOne[dimension] = {dataSetOne, dataSetTwo};
end MyDataArrays;
