[Help-gsl] Integration routine qawc

[Silke Diedenhofen]

Hello!

I have another problem using the integration routine qawc:
gsl: ../integration/qawc.c:213: ERROR: maximum number of subdivisions reached
Default GSL error handler invoked.
abnormal program termination

and this is the part of the sourcecode, where the integration is performed:

 double f (double y, void * params) {
      double Wg = *(double *) params;
      double omega_0 = *(double *) params;
      double h_quer = *(double *) params;
      double theta_1 = *(double *) params;
      double tmp_7 = *(double *) params;
      double tmp_6_1 = *(double *) params;
      double tmp_6_2 = *(double *) params;
      double theta_2 =  *(double *) params;
      double f = (tmp_7/sqrt(y))*(tmp_6_1*(sqrt(theta_1) *
(pow(gsl_sf_airy_Ai_deriv((Wg-h_quer*sqrt(y))/(h_quer * theta_1),
GSL_PREC_DOUBLE), 2)- (Wg-(h_quer*sqrt(y)))/(h_quer * theta_1) *
pow(gsl_sf_airy_Ai((Wg-(h_quer*sqrt(y)))/(h_quer * theta_1),
GSL_PREC_DOUBLE),2))-sqrt(sqrt(y)-(2*PI*C/0.00000087))/PI) + tmp_6_2 *
(sqrt(theta_2)*(pow(gsl_sf_airy_Ai_deriv((Wg-(h_quer*sqrt(y)))/(h_quer *
theta_2), GSL_PREC_DOUBLE), 2)- (Wg-(h_quer*sqrt(y)))/(h_quer * theta_2) *
pow(gsl_sf_airy_Ai((Wg-(h_quer*sqrt(y)))/(h_quer * theta_2),
GSL_PREC_DOUBLE),2))-sqrt(sqrt(y)-(2*PI*C/0.00000087))/PI)); 
      
      return f; } 
 gsl_integration_workspace * w = gsl_integration_workspace_alloc (100000);
       gsl_function F;
       F.function = &f;
       F.params = &Wg, &omega_0, &h_quer, &theta_1, &tmp_7, &tmp_6_1,
&tmp_6_2, &theta_2;
gsl_integration_qawc (&F, omega_g, 7.24e30, omega_0, 0, 1e-3, 10000, w,
&result, &error);

What do I have to change to do this integration?

Thank you!
