Possible infinite loop in structural_application
« on: May 02, 2016, 11:57:14 AM »
Dear all,

I just detected that in the tensor_utility of the structural_application there is (at least) inconsistent loop:

the file:

the loop:

    static inline void Contraction_Double(Fourth_Order_Tensor& Fourth_Tensor, Second_Order_Tensor Second_Tensor, Second_Order_Tensor Result_Tensor)
        unsigned int size = Second_Tensor[0].size();
        for (unsigned int i=0; i<size; i++)
            for(unsigned int j=0; j<size; j++)
                for (unsigned int k=0; k<size; k++)
                    for (unsigned int l =0; j<size; l++)
                        Result_Tensor(j)= Result_Tensor(j) + Fourth_Tensor[j](k,l)*Second_Tensor[k](l);

The underline code should be "l<size" in my opinion.
It looks like this was introduced in rev 1141, so it has been a long while there without nobody complaining about it.
Please, if you use the structural_application take this into account.

Dear Carlos,

   I agree that the code looks wrong. I believe that this function is not being used, otherwise someone would have an error. My proposal would be to comment it out entirely, putting a comment of where the problem is.

if someone is actually using it an error would pop up...

what do you think?
