Yes, I did go ahead and submit a product suggestion.

Hello , iam from colombia.
i am writing code in labview for develop the finite element method. i will devolop code for calculate estress, strain, forces, and FS wilth element unidimensional beam and truss, bidimensional CST, LST, Q4, Q8 and Q9. it is possible !!! if u know the mathematical formulation.

Sebastian,
LabVIEW does not have a specific toolkit used for FEA, as mentioned above. Multiple product suggestions have been made for this toolkit, and I encourage you to make another. You do have the ability to create your own application to run FEA for all of the referenced simulations, but this would require a lot of overhead and development time. If you want to go this route, I recommend you take a look at the Partial Differential Equations VIs. If you do end up creating an application to run FEA, I am sure it would be very coveted.
Best,

Hello Jason
it that you told me is really true. Other companies as abaqus, ansys, they have many people developing day a day code for aplications about finite element method, for a one person it is very slow, it take very time.
if you like when i finish my research where i use labview for write code of finite elements, i can send you it.
thank you for the tools for solve differrencial equations
sorry for my english.

Sebastian,
I have written a thermal simulation and parts of a fluid dynamics simulation in LV. Neither is general purpose and neither is anything I can publish at this time.
Tips: If the changes are sufficiently small (from time step to time step and cell to cell) you may be able to simplify the differential equations to difference equations or even algbraic equations. If you can do this without loss of accuracy or generality, you may get substantial speed improvements.
Pay attention to memory management so that you do not create unnecessary copies of large datasets. NI has published a white paper on the management of lareg datasets. It is several years old but still very valuable.
Make sure your algorithms test for convergence or timestep errors. If possible try to adapt the calculations to prevent or overcome such errors. There are books which describe methods for doing this.
Please keep us informed of your progress.

hi how are you , i want give a advance for the structure of code:
When you speak about simplify the differential ecuation is totaly true. my purpose is reduce the computational cost, using the way functions for give numeric solution a diferential ecuation, remove the older, the most amount possible of ceros of the stiffness matriz, further of other artifices.
while less nodes number, less operations, less computational cost, more small the stiffness matriz, it will be more efective and eficient.
