# CFD AcuSolve Reader

AcuSolve results for steady state, transient and moving/deforming mesh analyses can be imported and post-processed using the AcuSolve Reader (*.log) in HyperView.

All element types available in AcuSolve are supported by the AcuSolve direct results reader (*.log).

Activate the Load Model check box to enable the Load Model panel and then click on the file browser button to open the Load Model File dialog, where you can select the *.log file of the CFD analysis.

The AcuSolve reader can be explicitly selected by clicking on the Files of type: pull-down menu and selecting AcuSolve Reader (*.Log). Once the AcuSolve reader has been selected, only the AcuSolve *.log files will be displayed in the directory.

The selected *.log file contains a link to the AcuSolve result file directory, in general ACUSIM.DIR, from which the relevant result data will be extracted.

After loading the result files, the result types for nodal_output and for extended_nodal_output will be displayed in the selection list for contour plotting. The derived_quantity_output is included in the extended nodal output.
