FLUENT 5.2.3 running on PIII 733

Burley Wang

I was really frustrated when I spent a whole day on trying Fluent 5.2.3 running on a new NT Server.

1. the hardware configuration of the PC is : 512MB RAM, PIII 733 EB MHz, 2*9G SCSI HDD,and Matrox AGP 400 graphic card w/ 16M 2. WindowsNT 4.0 server with service pack 3 3. works well when running Gambit 4. in the environment of fluent 5.2: after I changed the unit of the mesh and zoom the meshes, it may show:

Error: Floating point error: overflow,

for a 3-D mesh,the error appears when the scale is abour 1e-4(m)and for a 2-D mesh, the error appears when the scale is 1e-5 (m)

all the .cas files or .msh files I used were all calculated sucessfully on the old running environment,which is:

1. PII 350, 64MB RAM, 8GB IDE HDD, Winfast AGP graphic Card 2. same version of fluent 3. same NT and the service pack

I've reinstalled NT server or NT worksattion, they just help nothing.

pls help me, any suggestions, thanks a lot
