What steps will reproduce the problem?
1. with the current _test function
2. create a stiffness matrix which results in missing entries for the last 
element

problem lies in the get_section function of the assembly module

What is the expected output? What do you see instead?
entries with 0 for node number 2

I think its with the mid side nodes because matrix size is around 108x108 (not 
exact)
but can you please get one without mid side nodes and put it to the 
07_Testcases folder in the repository

Yes, you are right, it must be 66x66.  The element type in input file has to be 
B21.
I will change the input file as well.
And put it the generated matrix into 07 folder
