updateParameter Problem with v. 1.7.4

[mebowers]

Hey folks,

I stumbled upon a possible bug with v. 1.7.4 Can anybody run updateParameter in 1.7.4.? Apparently the format....

updateParameter -material $tag -refB value

is no longer valid in 1.7.4. It is looking for an integer first, not -material.

I can run the same file in 1.7.3 but not in 1.7.4. It should be noted that I am using OpenSees 1.7.4 with Vees.

Thanks,
Matt Bowers

that particular usage was a terrible hack of the parameter & updateParameter command .. try updateMaterials with the same options.

I tried your suggestion...

updateMaterials is definitely recognized by v1.7.4 but not the -refB parameter identifier (it appears). The message NO RESULT appears, and the parameter is definitely not updated.

I tried some other values -B, -refBulkModul etc. but nothing seemed to work. Something is definitely wrong, is there another command to use intstead of -refB?

post a 2 element example that i can have a look at.
