Hello,
I'm testing a simulation tool for FMI Models. I created multiple Models via OpenModelica to test basic functionality.
Somehow the exported FMU returns invalid results
The Model calculates the sum and product of the current time.
Code:
model OpenModelica_Simple_Add_Mult_Auto
output Real sum(start = 0);
output Real prod(start = 0);
algorithm
sum:=time + time;
prod:=time * time;
end OpenModelica_Simple_Add_Mult_Auto;
The Results (FMU exported by OpenModelica, version 1.8.1 r11643 AND 1.9.0 r12942)
Code:
Step 0000: sum: 0.000000; prod: 0.000000
Step 0001: sum: 0.000000; prod: 0.000000
Step 0002: sum: 0.000000; prod: 0.000000
Step 0003: sum: 0.020000; prod: 0.000100
Step 0004: sum: 0.040000; prod: 0.000400
Step 0005: sum: 0.060000; prod: 0.000900
Step 0006: sum: 0.080000; prod: 0.001600
Step 0007: sum: 0.100000; prod: 0.002500
Step 0008: sum: 0.120000; prod: 0.003600
Step 0009: sum: 0.140000; prod: 0.004900
Step 0010: sum: 0.160000; prod: 0.006400
The results using Dymola 2013 to export
Code:
Step 0000: sum: 0.000000; prod: 0.000000
Step 0001: sum: 0.020000; prod: 0.000100
Step 0002: sum: 0.040000; prod: 0.000400
Step 0003: sum: 0.060000; prod: 0.000900
Step 0004: sum: 0.080000; prod: 0.001600
Step 0005: sum: 0.100000; prod: 0.002500
Step 0006: sum: 0.120000; prod: 0.003600
Step 0007: sum: 0.140000; prod: 0.004900
Step 0008: sum: 0.160000; prod: 0.006400
Step 0009: sum: 0.180000; prod: 0.008100
Step 0010: sum: 0.200000; prod: 0.010000
The results using OpenModelica somehow lags behind.
Does anyone have the same problem?
