SUMMARY

Meshing failures in Ansys Workbench can occur due to complex geometries and improper mesh control settings. The user experienced a failure while attempting to use the "Multizone/hexa" method, but found success with the "Hex Dominant" method. An alternative solution involves slicing the geometry into multiple pieces in DesignModeler and creating a "Multi-Body Part" to simplify the meshing process. These strategies can effectively address common meshing issues in Ansys Workbench.

PREREQUISITES
  • Familiarity with Ansys Workbench interface
  • Understanding of mesh control methods, specifically "Multizone/hexa" and "Hex Dominant"
  • Basic knowledge of geometry manipulation in DesignModeler
  • Experience with creating Multi-Body Parts in Ansys
NEXT STEPS
  • Research the "Hex Dominant" meshing method in Ansys Workbench
  • Learn how to effectively slice geometries in DesignModeler
  • Explore best practices for creating Multi-Body Parts in Ansys
  • Investigate common causes of meshing failures in Ansys Workbench
USEFUL FOR

Engineers, simulation analysts, and CAD designers who are working with Ansys Workbench and seeking to improve their meshing techniques and troubleshoot common issues.

I have been working on example of the book of ansys workbench by H.H.LEE but I tried to do different mesh using : mesh control <method<Multizone/hexa unfortunately I got an error message saying that the mesh failed and can't be performed. Does anyone who why does meshing might fail and what is the alternative in such situations

I've used the "Method - Hex Dominant" meshing with reasonably complex geometries with good success, try that out and see how it goes. Your other option is to slice the geometry into multiple pieces in DesignModeler and then creating a "Multi-Body Part" with the resulting sliced solids to try simplifying the meshing requirements.

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
