Experience with the p-Version Program PROBEby D. A. Dunavant, Noetic Technologies Corp, United States,
Document Type: Proceeding Paper
Part of: Computer Utilization in Structural Engineering
Abstract: The conventional approach in the FEM is known as the h-version, in which the solution accuracy depends on the size h of elements. The alternative approach is the p-version, in which the solution accuracy depends on the polynomial degree p of the displacement function of the elements. Research on the p-version has been ongoing at Washington University in St. Louis since 1970, and at several other institutions since then. Noetic Technologies Corporation was formed in November 1984 to commercialize the p-version, and the program PROBE was first released in April 1985. Subsequent releases were made in August 1986 and December 1987, and future releases are planned. This paper will discuss experiences with the development and marketing of the commercial program PROBE. Comparisons will be made to commercial h-versions programs from both the developer's and user's viewpoint. Present capabilities as well as plans for future capabilities will be discussed.
