COMPUTER AIDED DESIGN LABORATORY
CAD
laboratory is equipped with a computer network with necessary hardware
and civil engineering software specializing in structural analysis,
drafting and developing solutions for industrial applications. Some
of the commercial finite element packages available at CAD Lab are
SAP2000, MIDAS, GRASP and FLAC. In addition to that, some in-house
codes are also available for various structural analysis and design
purposes. Furthermore, CAD laboratory provides working environment
for undergraduate and post-graduate research studies
Computer Aided Design (CAD) Laboratory provides essential computational services for the
teaching, research and consultancy activities of the Department of Civil Engineering, University of
Peradeniya. Currently, it consists of the following equipment.
- Available laptops – 82
- Multimedia Projectors – 04
- Workstations – 05
- NEC Computers – 04
- HP Computers – 02

The most recent addition to the CAD Laboratory is the Advanced Numerical Simulation Center
which facilitates high end numerical simulations for the teaching, research and consultancy
activities of the Department of Civil Engineering, University of Peradeniya. This center was
established with the generous funding of PEFAA parallel to the diamond jubilee of the Faculty of
Engineering University of Peradeniya.
