Error in Prism Ratio Computed1 Attachment(s)
Has anyone seen the error associated with the attachment? In case attachment doesn't come through I will describe.
I used prism compute parameters to compute the exponential height ratio of an initial height of 1e-7, 50 layer, total height prism of 0.001. The height ratio came back as -1.#IND I changed it to compute the initial height using the same parameters, and got the correct initial height (1e-7) when i input the ratio of 1.15884 Trying it with slightly different settings, I used prism compute parameters to compute the exponential height ratio of an initial height of 1e-6, 50 layer, total height prism of 0.006. The height ratio came back as 5.85714 which is clearly incorrect. I once again changed it to compute the initial height using the same parameters, and got the correct initial height (1e-6) when i input the ratio of 1.1445. The two methods should be the same, but ICEM seems to be having trouble solving for the height ratio for these cases. |
