    If too many failed elements, then try tetra remesh or tetramesh optimization option.If only few ,then by manually moving nodes would be fine.Btw if tet collapse is greater than 0.1 ,then it fine for analysis.If using Optistruct for analysis, then activate PARAM : CHECKEL : NO for running analysis without element quality check.
