An effort is proposed to bring the capabilities and advantages of the meshfree method within a dedicated open-source framework for use in earthquake engineering applications.

The open-source RKPM-based meshfree (Chen et al., 2013, 2017a, b; Chen and Belytschko, 2015) computational framework (Huang et al., 2019) for linear static analysis was developed by JS Chen and co-workers. The RKPM2D is available at:

Currently, the RKPM2D is being extended to conduct nonlinear large-strain dynamic analysis. As such, a representative simulation of earth embankment subjected to earthquake loading is presented to demonstrate the computational capabilities of this extended RKPM open-source code.
