Cheat sheet for finite element
(OP)
Hello everybody
I was searching for a good cheat sheet for FEM to review it , but could n't find a good one , please if you have any access or link , or you can share it with me

RE: Cheat sheet for finite element
are you looking for a step-by-step guide for making an FEM ?

RE: Cheat sheet for finite element
actually I was studying this file attached , on page 19 there is a function defined that I don't understand , I think the rest is straight forward , and if I undeerstand this 1D , the 2D would not be so much different , and what is the difficulty in solving the matrixes ?
I appreciate all the responses and answers
thank you very much
RE: Cheat sheet for finite element
what was on pg 19 that you couldn't follow ?

RE: Cheat sheet for finite element
well I am trying to understand this code so will understand the Fem code writing well , just as a start , in that page the IEN and LM are two matrices calculated that for LM is written like :
global degree-of-freedom=LM (local degree-of-freedom, element number)
that when a node 's degree of freedom is one , the IEN and LM are identical , (why ?) , then I don't get the two dof node condition
RE: Cheat sheet for finite element
global dofs are based on an external co-ord system, ie components of rod load.
the element stiffness matrix is in terms of local dofs.
the structure stiffness matrix is in terms of global dofs.
that said i disagree with "when a node 's degree of freedom is one , the IEN and LM are identical".
global and local dofs are identical (IMO) if the element is aligned to a global axis.

Thank you for the responses , but I really wish somebody open the pdf file I uploaded and tell me what is happening step by step in the matlab file , I mean how we form the matrices and the solver , like page 21 , this could be a good guide for me to understand both coding and FEM steps
