Error Solving Semi Elliptical Crack

      Actualmente estoy realizando mi Trabajo de Fin de Máster utilizando la herramienta de ANSYS. En concreto, estoy utilizando el análisis Static Structural. Tengo una geometría que simula un diente con una superficie bastante irregular y estoy intentando crear una grieta con la herramienta de Semi Elliptical Crack para después observar esos análisis. La herramienta me genera la grieta, pero al darle a SOLVE para que me calcule el sistema y me muestre alguno resultados me salta este error en la información de solución. Por que podría ser exactamente, o como podría ver cual es el problema de manera más clara para solucionarlo? Habría alguna manera de solucionarlo?

      Translated: I am currently doing my Master's Thesis using the ANSYS tool. Specifically, I'm using Static Structural analysis. I have a geometry that simulates a tooth with a fairly uneven surface and I'm trying to create a crack with the Semi Elliptical Crack tool and then look at those analyses. The tool generates the crack, but when I click on SOLVE to calculate the system and show me some results, this error jumps out in the solution information. Why could it be exactly, or how could I see what the problem is more clearly to fix it? Would there be any way to fix it?

      Hello,

      Please see if the following link helps on defining coordinate system and also a forum thread on visualizing different local coordinate systems help:

      SMART Crack Growth with Semi-elliptical crack (ansys.com)

      The second link will help you in visualizing the coordinate systems, if they align with crack front.
