Abstract

In this presentation, the Immersed Structural Potential Method (ISPM) will be presented along witha series of numerical enhancements. A key aspect of the success of immersed methodologies is theaccurate description of the immersed structural domain. In the case of the ISPM, this relies upon theaccur...
