Hi, I am trying to fit a prony series to set of data(modulus and time). I want to use curve fitting to fit the experimental data set. I am confused about the time constants. Is there a way I can find the time constants without having to do it by hit and trial method. Is there a way by which I...

Hi, I want to conduct an experiment where I want to maintain water temperature at a particular value. Its an experiment for a project and I have to do it at home. Is there any ideas of how I can keep the temperature constant(may be for 45 min). I have to do the experiment at temperatures...

I have installed LS Prepost beta(3.0). I was trying to work on the ball impact tutorial. I used the old to new tab to get to the GUI interface. I could find the mesh tab and gave the dimensions. It asks to then click on mesh render. I did not find any tab like mesh render. I need to know know...

Let me rephrase the question in terms of temperature. When we solve MV(0)+KU(0)-F(0)=0 for V(0), where V(0) is the dT/dt at time t=0 and U(0) being the temperature. Do we impose the secondary boundary conditions like flux in our F(0) vector and also the given temperatures in our U vector. I am...

@Brian, y was your response like this? Was my question so annoying?

Thanks. It is a numerical technique to match in time.right? Let's say I have formed my mass matrix and my element matrix. If I know the initial boundary conditions, let's say primary as well as secondary boundary conditions. When we solve MV(0)+KU(0)-F(0)=0 for V(0), where V(0) is the velocity...

Hey, enough of criticism. Its not that if you give a code, it will be terrible. I know that I need to do my own code, which I am doing. Even if you give me a code, first I need to understand your code to implement it, which for sure won't be easy. Everybody has his/her own way of coding. Neways...

I need a fem code either in MATLAB or fortran to refer to as I am stuck at some places. Please help.

Homework Statement det(K-lambdaM)=0 K is stiffness and M is mass matrix Homework Equations How do I make sure that Q'*M*Q=I Where Q is the matrix whose column entries are the eigen vectors. The Attempt at a Solution I want to know how to do it without MATLAB help. Is it always...
