Dear All,

This is the error i am getting while executing the Modal Analysis.

LUMPED MASSES
Mass, Direction, Start, End, Inc
0 , , 0 , 0 , 0
SYNTAX ERROR: Possibly lower case input, or illegal characters.

Please help me how to resolve this problem.

Put something between those two commas.

SIr,

I tried but again getting same error.

Send the job in to techsupport@coade.com, although your "direction" value looks wrong. It should be "X", "Y", "Z", or "all".

Daman,

I interpret your input as:
0 Kg in the 0 direction from nodes 0 to 0.

That does not look like proper input to me.

Sir,

You are right.

My intention is that while executing the modal analysis, Caesar automatically takes the static model loading.

Daman

If you are trying to set the (nonlinear) support configuration based on the operating state, that is specified on the Control Paramaters tab.

I see no reason to modify the mass distribution. I suggest you delete that line of data.

Sir,

I did same as you mentioned above. It's ok.

But, now i am getting the new error.

Hello Sir,

Now i can execute my Modal analysis.

Please confirm the input data for the Modal analysis.

1. I deleted all the Nonlinear effect from the system (like +Y converted into Y, Gaps & friction are removed from the piping model)
2. No lumped mass added in the system
3. Cutoff frequency considered as 33 Hz.
4. Max. No. of Eigenvalue calculated-10


Following observations made while reviewing the Dynamic Boundary condition report.

1. Why Disp. Reaction means Anchor shows negative stiffness value. Value reflected in the mail.

2. The static model contains the snubber. But in case of model analysis we are manually entered the snubber including its stiffness. Why the report shows Rigid & the dynamic snubber.

3. We refer mass model for the displacement. Its total displacement including all the 10 modes.
