To achieve this we have extended our existing YAML text data file format.

A restart data file (.yml) that defines the modifications to the input data for the restart analysis.īecause a restart typically changes only a small number of data items, we want the restart data file to contain only the data that is different from the data in the parent.

A parent simulation file (.sim) that is used to determine the initial conditions of the restart analysis.yml) that defines the input data for the parent analysis. In order to define a restart analysis we need the following: Model data may be modified in a restart analysis. In a restart analysis, the initial conditions and state are determined by the output of a prior analysis (which we refer to as the parent analysis). Restart analysis is a common feature in many finite element codes, but for various historical reasons, OrcaFlex has not implemented restart analysis until now. Restart analysis, variation models, and change tracking What follows is a brief introduction to each of the new features that we consider to be of most significance. All new features are fully documented in the what’s new topics: As always there are more enhancements that are not listed here. These are the most significant developments, in our opinion. Embedded Python scripts as an alternative to external files.Wire frame drawings specified by panels.Performance improvements for wave time history analysis.Hysteretic and externally calculated axial and torsional line stiffness.Restart analysis, variation models, and change tracking.Version 11.1 introduces much new functionality, including: We plan to make the next release in the traditional Q4 slot, later this year.Īll clients with up-to-date MUS contracts will receive, in the week starting 22 nd February, an e-mail with instructions on how to download the new version.

However, we delayed the release in order to complete the restart analysis development. We originally planned to release 11.1 in Q4 of 2020. The software was finalised and built on 12 th February. We are very pleased to announce the release of OrcaFlex version 11.1.
