What's the Optimal Shape Function for Phase Field Simulations in FEM?

AI Thread Summary
The discussion focuses on identifying the optimal shape function or element for phase field simulations in finite element methods (FEM). Participants emphasize the importance of experimenting with different element types, as benchmarks for this specific analysis may be scarce. The conversation highlights the need for practical comparisons of results from various shapes used in simulations. Users are encouraged to share their findings and experiences with different shape functions. Ultimately, the goal is to determine the most effective approach for phase field simulations in FEM.

What have you found so far? What shapes are typically used for which types of simulations?

If you can't find any benchmarks for this type of analysis, it would be best to just try different element types and compare the results (i.e. do the benchmark yourself).

little otherwise wouldn't have asked here
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
