WebJun 4, 2012 · There are many ways to avoid that. I will try to explain some of them: set the substeps size to a fixed value, by modifying "Analysis Settings" > "Step Controls" "Auto Time Step" to "OFF" and choosing a fixed substep size (or number of substeps) or; set a range for the substep size by setting the same parameter to ON and choosing a range for ...

WebJan 20, 2016 · An example is shown here, where a safety factor is calculated based on a value of 6,200 psi. The safety factor looks at the First Principal Stress output, computes the safety factor, then caps the display at 7. Values less than 0 psi (compression when looking at the First Principal Stress) are set to the highest safety factor allowed (7 in this ... WebI know very little about explicit in ANSYS, but the requires time step is related to the material density and smallest element size. Basically, the time step has to be smaller than the time it takes for a load wave to propigate across the smallest element, and the speed of wave propigation is related to material density. if the time step is larger than the time it takes …

By selecting auto time scale in solver control and using time scale factor as 1e-4 which makes the time step very small. Here we can provide the …
WebNov 3, 2024 · It seems like the best approach to getting a stable time step is to let ANSYS program control it, ... use a time safety factor of 1, add a simple displacement to the element and solve, then time increment in POST still does not equal t = (1)*L/c . Am I missing another factor or is CFL just a starting point to work from? November 3 ... WebHari Krishnan Ramachandran. In Ansys, the safety factor is always shown between 15 and -15.
