What's the best shape function/element in finite element methods for phase field simulation?
What's the Optimal Shape Function for Phase Field Simulations in FEM?
- Thread starter feynman1
- Start date
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.

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).

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets.
I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads:
"The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. "
3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
Scenario 1 (figure 1)
A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material.
The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm).
At this level of stretch, the load cell reads 45N tensile force.
Key numbers...
