Sphere in STAR-CD

sameer jaju

Hi, I am creating a simple sphere in STAR-CD. I can create it with the sperical coordiates system. After creation, when I go to check cells, it shows negative volume error. I did check for left and right handed cells and then made all right handed. But then it shows some crack errors. After that if I use VMERGE ALL , message comes.. vertices deleted. Then my whole geometry vanishes. And if I check by COUN CELLs, the message shows the celltype and number of cell and number of cell in cplot as expected. still I can not see geometry. Please let me know if anybody knows how to remove error in Sphere in STAR-CD. Thank you in advance
