FELICITY

Finite ELement Implementation and Computational Interface Tool for You

Description

This is a MATLAB/C++ code for solving PDEs that are discretized by a finite element method on unstructured grids. It automates assembly of a variety of FEM matrices using a straightforward syntax and automatic code generation. The resultant matrices can be manipulated by MATLAB for ease in solving a PDE on a triangular (or tetrahedral) mesh. For example, you can solve Laplace-Beltrami on a 2-D surface in 3-D. You can do higher order geometry (i.e. iso-parametric mappings). You can assemble matrices (bilinear and linear forms) on 1-D curves embedded in a 2-D mesh. There is also an implementation of longest-edge bisection for 2-D triangular meshes for any given initial mesh.

Hi Shawn

I have a 64-bit version of matlab installede and tried to install Visual C++ 2010 Express from the following link:http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express.
When I wrote m -setup in the command window it could not find the compiler. Do you know if I need a 64bit compiler?

[Shawn Walker]

YES, you do need a 64-bit compiler. When I tested this on Windows 7, I installed Visual C++ express edition (64-bit), and it worked.

Hi Shawn

Which version of Visual C++ edition did you install? In fact I have a 64bit version of matlab R2010a on a Windows 7 computer. Could you send a link where I can download a 64 bit version of Visual C++ express for free?

[Shawn Walker]

Here is the link I found:

Visual C++ 2010 Express:

http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express

It says that it supports 64bit versions, and Windows 7. You may have to register as a user, but that isn't a big deal. Once you have it installed, MATLAB should see it by typing "mex -setup".

[Shawn Walker]

Let me add another comment. You have to install TWO things (separately) to make MATLAB see MS Visual C++. They are:

1. Microsoft Visual C++ 2010 Express

2. Microsoft Windows SDK 7.1

Both are free and must be installed in that order (sorry I forgot about this).

The following link should be useful for those who want to use MS Visual C++ (Windows):

Hi Shawn

Now I installed the following version of Microsoft Windows SDK 7.1

x64 ISO File Name: GRMSDKX_EN_DVD.iso

CRC#: 0x04F59E55

SHA1: 0x9203529F5F70D556A60C37F118A95214E6D10B5A

First I installed Microsoft Visual C++ 2010 Express as you proposed, but still it cannot find the C++ compiler in matlab when I write mex -setup

[Shawn Walker]

I'm not sure what is wrong. Make sure you verify that your version of MATLAB supports the compiler. If it is a recent version R2010 or later, then you should be fine. But double check the version/compiler compatibility on the MATLAB web site.

Also, did you try this link:

http://www.mathworks.com/support/solutions/en/data/1-ECUGQX/

They walk you through the full install.

If that doesn't work, you should email the MATLAB helpdesk.
