DataPower software Family

DataPower Server

DataPower Server is stand a lone program sending synchronised viscoelastic data to any client program in same or remote PCs by TCP/IP protocol.

DataPower Server is based on the RheoPower principle.

Computer Assisted Engineering (CAE) Client programs are not platform depended.

RheoFlow CAE Client program is developed for calibration uses.

RheoFlow can simulate basic flow channels by DataPower Server data.

DataPower Server can make very fast data feeds according data requests for any CAE client software.

DataPower Server program sends viscoelastic synchronised data computed from a polymer material datafile. The use of Server is very simple and only maintain is to change material data files for new polymer types.

Performance

DataPower generates in few milliseconds the data response. On IP/TCP network connection DataPower can serve many clients simultaneously located on separate PCs up to supercomputers. DataPower is stand a lone server program by TCP/IP connection made by CAE, Computational Fluid Dynamics (CFD) and Computer Aid Design (CAD) client programs. DataPower Server gives data:

At different temperatures,

pressures and

with known shear history.

Complete wide Functions as:

Viscosity flow curve as a function of shear rate.

Transient viscosity as a function of time or state.

Relaxation modulus.

Orientation degree at different rates or states.

PVT data

Measured Speed

In the same computer 420 data services in a second means average response time 2.4ms.

In the Intranet connection 100 data services in a second means average response time 10ms.

In the Internet connection 10 data services in a second means average response time 100 ms.

System Requirements

Intel Pentium 300 MHz or faster.

Windows 95/98, NT 4.0, 2000 or Millenium/XP.

Ram 8MB but 50MB recommended.

Measured viscosity from 130^oC to 250^oC at 10^oC steps for LDPE H1840 by BASF marked by points. Modelled viscosity curves from fit at 190^oC are marked by lines. Max error is 5% in the above figure.
