[esp-r] pressure coeffcient calculation error

[NALIN SWAROOP]

Hello all

I am trying to calculate pressure coeff. values using esp-r and then
adding it to a new database but every time a define a coordinate and try
to calculate the pressure coeff. it gives me the following error.

Failed in.../zones/1floor.geo conversion of no. pressure item value in -0.100

In ..zones/1floor.geo error reading press db ln1 EOF sensed

What can be the problem and why is trying this in geometry file??

Regards

Nalin
